The day after Colleen Ritzer's Oct. 22, 2013, murder in Danvers, Mass., Philip Chism allegedly confessed to killing his teacher, but an Essex County Superior Court judge threw the teen's statements out yesterday. Chism, who was 14 at the time, was not adequately informed of his Miranda rights and did not waive those rights "beyond a reasonable doubt," Judge David Lowy said, per the Boston Globe.

NECN fleshes that out: Lowy wrote that it was "readily apparent" Chism's mother did want an attorney present, and he notes Chism didn't seem to be paying close attention when his Miranda rights were read. Chism has pleaded not guilty to murder and rape charges and his trial is scheduled for Oct. 7, reports the AP.

Typically when people hear that a suspect has made a confession, they cannot fathom how the person could not be guilty of the crimes. However, there's a significant amount of cases where the confessions were coerced out of innocent suspects. A good example of this is the "Central Park Five" case. I highly recommend watching the Ken Burns documentary on it. http://en.wikipedia.org/wiki/The_Central_Park_Five
